I sent this question some time ago, but had no response from anyone. I'm
not looking for refs., anecdotal or even intelligent speculation OK.

Hi, all. My daughter has a question. She sometimes uses a
device to shave armpits that pulls the hair out by the roots. She was
warned that she may damage breast tissue with it. Anybody hear
anything about this? TIA, Judy Knopf in Beer Sheva, Israel
